REINHOLD HANDEL, OF LEIPSIC, SAXONY, GERMANY.

APPARATUS FOR STIRRING AND MIXING FLUIDS, POWDER, 80C.

SPECIFICATION forming part of Letters Patent No. 421,704, dated February 18, 1890.

Application filed July 22, 1889. Serial No. 318,271. (No model.) Patented in Germany February 27, 1888, No. 44,413.

To all whom it may concern.-

Be it known that I, REINHOLD HANDEL, of Leipsic, in the Kingdom of Saxony and German Empire, have invented a new and Improved Apparatus for Stirring and Mixing Fluids, Powder, and Similar Substances, (for which I have obtained Letters Patent in Germany, dated February 27, 1888, No. 44,413,) of which the following is a full, clear, and exact description.

The object of my invention isto provide an adjustable device whereby powder, dough, thick liquids, and similar materials may be throughly commingled or mixed in any suit-- able receptacle.

' A further object is to furnish an adjustable stirring-machine which will operate its stirrers in different planes within the receptacle that holds the materials operated upon, and also that will remove any of the liquid or plastic compound from the upper edge of the receptacle, which may be there deposited by the stirring. operation.

l/Vith these objects in view my invention consists in certain features of construction and combinations of parts, which willbe here'- inafter described, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the device in position for use. Fig. 2 is an end elevation of the same. Fig. 3 is a plan view of the apparatus; and Figs. 4, 5, 6, 7, and 8 are enlarged details of construction.

A is a bracket-frame, that may be clamped upon the edge of a table or other similar support, on which the receptacle for materials to be mixed is placed, as at B, Figs. 1, 2, and 3. To the vertical rod 01 there is attached a clamp device 6, by which the rod d can be end of the bracket h there is a bearing it, (see Fig. 6,) in which is journaled the cross head t. The top of the cross-head is provided with a bevel-toothed Wheel 0', which meshes with the bevel-wheel c, that is located on the end of the shaft b. Attached to the cross-head i there are arms r, which are formed as shown in Fig. 6. These arms are provided at the lower ends with the clamp devices k,which clamps k consist of the pieces Z (which have on the outer side a longitudinal groove intersected byatransverse groove) and the clamprings z, which have a square hole a, and are tightened or brought up in the said transverse grooves to the arms 0 by the screws and nuts m. The clamp-rings 2' receive the shafts of the stirrers. The arms 'r are pivoted to the cross-head 2', so that they can be adjusted in their spread and tightened up to the crosshead by their connecting-screws.

On the rod cl, between the clamps c and f, there is a clamp 0, which can be adjusted vertically. It carries two arms 19, connected as shown in Figs. 4 and 5, and another pair of similar arms are similarly connected to a suitable support at the other side of the table. The vessel B is held between these arms, as shown in Fig. 3.

When the apparatus is used, the three stirring wings or blades f are placed in the clamp-rings .2 at the required height and are fixed by tightening up the thumb-screws m. The stirring-wings are set in such a manner that their lower ends touch the inner surface of the vessel B at different parts, and they are set in motion by the fly-wheel a, through the shaft b, the bevel-wheels c c, and the crosshead i. The hinged arms 19 serve, by reason of their elasticity, to prevent the breaking of the vessel by the continuous striking of the stirrers against it. i

The vessel B is held to the arms 19 by the hooks 5, (see Figs. 3 and 8,) and owing to the spring of said arms the vessel may be kept perfectly and securely tight by moving the clamp 0 lower down on the rod d.

By means of the stirrers placed at different heights all the parts of thethick mass are brought relatively in contact with them, and consequently also with the atmospheric air; and it is evident that the Work of stirring and arms pivotally secured to the cross-head, areoeptaole for the material to be stirred, and vertically-adjustable laterally-extended arms engaging the receptacle at its edge to retain it in position, substantially as set forth.

In Witness whereof I have hereunto set my hand in presence of tWo witnesses.

REINHOLD IIANDEL.
